Abstract
The utility model relates to an oil film detecting sensor on the surface of water. The oil film detecting sensor on the surface of water is mainly applied to a floating mark type oil film alarm device on the surface of water in water area environmental protection. The sensor adopts the principle of the detection for conductivity. The utility model has the advantages of reliable work, high sensitivity, low cost and simple structure. The sensor is composed of a light float and a tenuous electrode. A liquid level can be tracked by the electrode, the electrode is matched with a conductometer or an exclusive circuit, and the oil film detecting sensor on the surface of water has the ability for detecting a thin oil film on the surface of water. The sensor has wide range of application for oil products. The sensor has good sensitivity for light diesel oil, heavy diesel oil, engine oil, crude oil, impurity oil and vegetable oil. The utility model is especially suitable for occasions whose water surfaces have fluctuation.
Description
The utility model relates to a kind of sensor, and it comprises: float and electrode.
Along with the oil pollution of ocean and inland waters more and more comes into one's own, to discharging oily sewage violating the regulations with accident contamination is monitored and in time report to the police, be an important technique measure in the environmental protection.The Kepner Spillalarm water-surface oil film alarm that existing alarm product has U.S. Kepner company to produce, what the sensor in this alarm adopted is ultraviolet-fluorescent principle; The 8330 type water oil stain alarms that Japan Yokogawa Motor company produces, what its sensor adopted is light reflection principle; What the sensor of the float type spilled oil on water surface alarm that Japan little wild field company produces adopted is that frequency electromagnetic waves can be by the principle of water surface oil decay; And the sensor in the alarm produced of French Nereides company adopts is that oil breaks it to special rubber diaphragm swelling and drives the principle of alarm.Above-mentioned various warning device, because the principle difference that sensor adopts, its sensitivity, the applicability to oil plant, reaction velocity, stability are all variant, cut both ways.
The purpose of this utility model is to provide a kind of that higher sensitivity,, reaction velocity wide to oil kind applicability are fast, good stability, low-power consumption, low cost, is adapted at the water-surface oil film detecting sensor of using under the water level fluctuation occasion.Be mainly used in the float type water-surface oil film warning device in the water environment protection.
The purpose of this utility model can reach by following measure: the water that contains impurity can conduct electricity, and its conductivity has notable difference with bubbling through the water column and have adhering oil film.Water-surface oil film detecting sensor described in the utility model promptly adopts to be measured between water body and the detected oil film, and conductivity has the principle of notable difference.
The water-surface oil film detecting sensor of making according to above-mentioned principle is made of float and electrode, and float is made by light weight insulating material, does not absorb water, not oil suction, corrosion-resistant and have certain rigidity.Floater Structure is divided two parts up and down, is provided with at the load line position of float to be no less than two tiny electrode.The float bottom is immersed in the water and is produced buoyancy; Buoy upper is taper, leaves the plane that can contact with the water surface in the end at awl, and the adhesion that produces between this plane and the water surface can make the float duty steady, guarantees that electrode is arranged in the critical surface of water and air and is difficult for breaking the water or immersing water.The extension line of electrode is drawn by the vertex of a cone of buoy upper by float inside, so that the output of detection signal to be provided.Sensor is a free-floating in the duty of the water surface, can not be connected with object on every side with fixing mode.
The purpose of this utility model also can reach by following measure: float is the stability of trying to achieve, and the ratio of the diameter of float and height should be between 1:0.3～1:1.5; Electrode material is selected corrosion resistant metal materials such as platinum, titanium for use; In order to improve the detectability of sensor to thin oil film, the exposed portions serve height of electrode should be greater than 1mm; It is soft that extension line is wanted, to reduce the additional force to float.
Fig. 1 water-surface oil film detecting sensor structural drawing
The utility model will be further described in conjunction with (accompanying drawing) embodiment:
The structure of sensor mainly is made of float and electrode as shown in Figure 1, and float divides the top vertex of a cone (1) and bottom buoyancy aid (2).Float is made by nonconducting light material, does not absorb water, not oil suction, corrosion-resistant and certain rigidity, gyro of outer appearance arranged.Its buoyancy is produced by water-immersed bottom, bottom buoyancy aid (2), and the buoy upper vertex of a cone (1) is used to avoid the resident of water and the power that has side effects.The height be no less than two electrode (3) less than 1mm is set at float load line position.Leave the plane that can contact with the water surface in the bottom of the top of the float vertex of a cone (1), the adhesion that produces between this plane and the water can make the float duty steady, guarantees that electrode is positioned at the critical localisation of water and air and is difficult for jumping out or entering the water surface.Extension line (4) one ends and electrode join, and the other end provides the output of detection signal.
The utility model is compared existing sensor technology and is had following advantage:
1, principle is simple, highly sensitive, and reaction speed is fast;
2, be suitable for the oil product wide ranges, to light, heavy diesel fuel, machine oil, crude oil, impurity oil and vegetable oil all have good sensitiveness;
3, simple in structure, cost is low.
Claims (4)
